MRS: Revenue Grade Split Core Current Transformers (mA Output)

Features

  • High accuracy, ± 0.2% / 0.5%
  • Ideal for use with Elkor Technologies Inc. Power Meters:
  • Current Transformers for the i-Spy AC Current Transducer.
  • Current Transformers for the i-Snail-X AC Current Transducer.

Product Decription

High Accuracy (exceeding Revenue Grade), easy to install, ideal for energy mangement applications, as well as accurate metering using Elkor's Power Metering devices. Unlike the standard 5A CTs, the MRS Current Transformers do not produce high voltage surge when opened . They generate a low energy mA output and no special protection and/or shorting blocks are required. Maximum open secondary voltage is clamped at about 15 V peak. These CTs are UL listed for easy installation in the field.
